1. 引入依赖

org.springframework.boot

spring-boot-starter-aop

2. 写切面

切面类需要加@Aspect和@Component注解

package com.test.demo.aspect;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;

import org.aspectj.lang.ProceedingJoinPoint;

import org.aspectj.lang.annotation.AfterReturning;

import org.aspectj.lang.annotation.Around;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

import org.aspectj.lang.annotation.Pointcut;

import org.springframework.stereotype.Component;

import org.springframework.web.context.request.RequestContextHolder;

import org.springframework.web.context.request.ServletRequestAttributes;

import cn.hutool.core.date.DateUtil;

import cn.hutool.extra.servlet.ServletUtil;

import cn.hutool.json.JSONUtil;

import io.swagger.annotations.Api;

import lombok.extern.slf4j.Slf4j;

@Aspect

@Component

@Slf4j

public class LogPrintAspect {

@Pointcut("execution(public * com.test.demo.*.*(..))")

}

@Pointcut("within(com.test.demo..*) && @within(org.springframework.web.bind.annotation.RestController)")

public void printParams() {

}

/**

*/

@Before(value = "printParams()")

public void paramsLog(JoinPoint joinPoint) {

ServletRequestAttributes requestAttributes =

(ServletRequestAttributes) RequestContextHolder.getRequestAttributes();

HttpServletRequest request = requestAttributes.getRequest();

Class> targetClass = joinPoint.getTarget().getClass();

if (targetClass.isAnnotationPresent(Api.class)) {

Api swaggerApi = (Api) targetClass.getDeclaredAnnotation(Api.class);

log.info("模块的中文汉字 {} , {}", swaggerApi.value(), swaggerApi.tags()[0]);

}

log.info("sign -- {}", joinPoint.getSignature());

log.info("请求地址:" + request.getRequestURL().toString());

log.info("请求方式:" + request.getMethod());

Map m = ServletUtil.getParamMap(request);

log.info("请求参数：{}", m);

}

/**

* 打印响应内容

* @param o

*/

@AfterReturning(returning = "o", pointcut = "printParams()")

public void methodAfterReturing(Object o) {

log.info(JSONUtil.parse(o).toJSONString(1));

}

/**

* 打印方法耗时

* @param joinPoint

* @return

* @throws Throwable

*/

@Around("printParams()")

public Object around(ProceedingJoinPoint joinPoint) throws Throwable{

long startTime = DateUtil.current(false);

log.info("执行方法：{},开始时间:{}" , joinPoint.getSignature().getName() , startTime);

}

}
